Contrast Enhancement for Lipid NanoParticles (LNPs) Characterization Using Transmission Electron Microscopy (TEM)

Using Transmission Electron Microscopy (TEM) for Chemical Analysis of Semiconductors

The transmission electron microscope (TEM) is an invaluable tool for the characterization of crystals, polycrystalline materials, biological specimens, nanostructures etc. It provides a wide range of different imaging modes with the ability to provide information on elemental composition and electronic structure at the ultimate sensitivity, that of a single atom. Convergent beam electron diffra...

Transmission Electron Microscopy (TEM) Characterization of doped α-Alumina

Qualitative EDX analysis: A map is acquired in low magnification. Results show equiaxial grains finely distributed through out the sample. In spite of the fact that simulations indicate no clear energetic gain or loss for cosegreation over single dopant segregation in this material, we observed that in all grain boundaries these two dopants (Y an La) are segregating together (figure 2). This co...

Scanning Transmission Electron Microscopy for Nanostructure Characterization

Study of Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM)

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are widely used in material science, metallurgy sicence and life science researches. TEM is an imaging technique where a beam of electrons is focused onto a specimen causing an enlarged version to appear on a fluorescent screen or layer of photographic film. SEM is a technique of electron microscope to produce high re...
